PAPER-FILE.

SPECIFICATION forming part of Letters Patent No. 283,667, dated August 21, 1883.

Application filed February 19, 1883. (No model.)

To all whom it may concern:

Be it known that we, FRANK Sennrrz and J os. Mints, citizens of the United States of America, residing at Cornell, in the county of Livingston and State of Illinois, have invented certain new and useful Improvements in Paper-Files, of which the following is a specification, reference being had thereinto the ac companying drawings.

This invention pertains to an improvement inpaper or letter files; and it consists in baseblock A, plate B, having lugs b and cars a, tubular pointed hooks C G, secured in hookpost E, spring D, eyebolt and spring-adjuster b, and in the combination and arrangement of the parts, substantially as hereinafter more fully shown and described. In the accompanying drawings, Figure 1 is a side View of our improved paper or letter file, showing one of the hooks sprung back. Fig. 2 is a plan view thereof, and Fig. 3 is a detailed section taken through one of the hookposts and spring. I

In carrying out our invention we employ a base-block, A, preferably oblong in shape. Upon this base is fastened a metallic plate, 13, having cast integral therewith ears a' at each end, and in these cars are pivoted the hookposts E, wherein are rigidly secured the tubular curved hooks O G. The metallic plate B is also provided with the lugs b, located at corresponding distances from the eyebolt and spring-adjuster I), as shown. The hooks 0 being tubular, and having oblique or sharpened points, the point of each hook, when the file is fastened, locates inthe tubular recess of its corresponding hook, the purpose of which is to hold the papers secure against loss, and to admit the papers being shifted from one hook to another.

The heel of each hook-post is slightly curved to admit its being readily and widely opened,

and when the file has been filled with papers the hooks are then looked in position by means of locking-pins thrust through orifices k in cars a, which precludes the accidental opening of the hooks by jarring or handling at any future time.

The flat plate-spring D, which projects beneath the hook-posts ll, is secured at its center to and upon the plate B by means of the eyebolt and spring-adjuster b. This eyebolt is passed through the spring D and plate B and screwed into the base-block A, and as the eye bolt is screwed h onie the spring is forced against the lugs b, and the ends of the spring are thrown up, and thus the elasticity of the spring is greatly increased, and by this means the spring may be adjusted from time to time to increase its elasticity as the papers are gradually filed upon the hooks.

It will be observed that the base-block A not only serves to receive the shank of the spring-adjuster I), which could not otherwise be operated to project through the thin metallic plate 13, but that it also serves to suitably sprung apart, and the files are thus lost therefrom, which is owing to the constant strain to which the springs are subjected. This disadvantage it is the purpose of our invention to overcome, and as suitable pinsare inserted in orifices 11- the security of the hooks rigidly in position is thus assured.

We are aware of the patent of G. W. Billow of January 14, 1873, No. 134,724, which we disclaim, wherein curved hooks are employed having pointed ends, which, being pivoted or hinged, may be readily sprung apart for reception of files, and then closed together, and these hooks he employs in connection with a metallic plate and springs adjustable thereon; but he does not show asupporting-plate with ears for pivoting the hooks thereto, cast integral with the plate, nor does he employ any locking device other than the fiat spring, which, when weighted with the files, soon loses its elasticity, and thus permits the hooks to be come disconnected and the files 10st therefrom. It is the purpose of our invention to remedy this imperfection.

Having thus fully described our invention, In testimony whereof We affix our signatures Io What We claim, and desire to secure by Letters in presence of two Witnesses.

Patent is The combination of the-base-b1oekA,p1ate FRANK SGHMITZ. 5 B, having ears a, provided with looking-pins JOSEPH MILLS.
